Grease a 9x9” casserole dish and preheat your oven to 350°.
Cut the steak into 1X4” strips.
Fold a slice of bacon in half and lay on top of each piece of steak.
Place an onion at one end of the bacon, and roll the meats up around it. Secure with a toothpick.
Place in rows in the casserole dish, season with salt and pepper, and cover with gravy. (Use less salt than pepper because there is already salt in the gravy.)
Cover the dish with aluminum foil and bake for 1 hour.
